Living walls come in many shapes and sizes, they require regular irrigation and frequent maintenance. The larger external walls usually require plumbing into the water supply, smaller stand alone internal units work with a small resovoir system. The water can be distributed by either direct micro piping or fabric wicking.
Considerations when considering a living wall or picture are size of room due to increased humidity, level of disturbance due to significant maintenace time required and species selection.
